Online banking won't work with terrible service

I am absolutely disgusted with absa. Since the launch of the new look, my online banking has been giving issues and now it refuses to work. I use the same pc as my husband. When he logs onto his account online he has the new interface however when I log onto my online banking I have the old interface. Once I an on my online banking and trying to pay, my sure check refuses to work. I accept the sure check, it comes through on my phone again and I accept it again and this carries on until the online banking says that it is not receiving the sure check. I have phoned and spoken to someone and nothing has changed? How must I do my online banking? Why is my account not up graded?
